UK gardening experts have revealed the surprising reasons they are urging Brits to let caterpillars eat their plants this spring. The advice comes from the Royal Horticultural Society (RHS) and The Wildlife Trusts, who are urging Brits to help support moths in their gardens this year. There are 2,500 species of moth found in the UK, according to both organisations. They are vital pollinators, which leads to plant growth and food production. Plus, they are a source of food for other wildlife, such as garden birds.
However, like many other species in the UK, their numbers have dwindled due to human population growth, urban developments and climate change. This is why both organisations are asking British gardeners to help. They report that moth populations have fallen by a third since the 1960s, a concerning drop. Gardeners are asked to choose plants that support moths and caterpillars when designing their garden this year. Plus, they are being advised to allow a little bit of nibbling on leaves and to rethink their relationship with these tiny creatures.
Many species of moth and caterpillar feed on just a small selection of plants, so it would be helpful to include them in your garden this year if you are willing to help.
Helen Bostock, RHS senior wildlife expert, said: “Moths have long played second fiddle to butterflies in the garden but understanding their value and needs, and that of their very hungry caterpillars, can support their recovery and help in creating a garden rich in biodiversity.”
Meanwhile, Vicki Hird, insect expert at The Wildlife Trusts, said: “Moths are stunning in name and beautiful by nature. The green, black and white merveille du jour looks as if it’s been exquisitely painted by an artist and the white ermine appears to be draped in a black-spotted cloak with a warm fur ruff.”

“It’s no wonder the French call moths ‘butterflies of the night’,” she added. “Even little brown moths can have wonderful, intricate markings.
“Making a simple moth trap is a wonderful way of enjoying these incredible creatures up close – before releasing it back into the wild. Let’s all help them in our gardens and enjoy the benefits they bring.”
According to the RSPB, there are several plants you can introduce to your garden to support caterpillars. These include:
